The Graphs Of Position, Velocity And Acceleration
The use of graphs is very common in science, statistics, economic and etc; in physics the graphs are use to illustrate and compare quantitative data of motion, time, velocity, etc. The graph illustrates the trend accurately, also the trend can be use to predict future outcomes. Graphs are a useful tool to have a efficient description in less words.
The Graphs of Position Graphs of position are a way to represent motion of an object or multiple objects in a graph using time and position. Time axis in a graph is used to measure motion in a specific time and position axis is used to measure distance. The time data and position data in a graph can be use to create a slope of time vs. position. …show more content…
The graph shows the data chart and a positive slope , it is easy to understand the graph and the direction of the straight slope. Another example using changing velocity(acceleration).In this changing velocity graph, the position of the object every second is different because the acceleration. In the acceleration graph the slope looks like a curved line because the speed is increasing every second. The two examples show a constant velocity graph and acceleration graph. Overall, the velocity graph has a straight line as slope because it has a constant velocity and the acceleration graph has a curved line because the acceleration. The speed can be use to determine the slope of the graph in motion.
Velocity graph Velocity is a vector measurement of the rate and direction of motion, and we calculate the velocity dividing the distance moved and the time it takes to complete the movement. V = d / t
An example of constant velocity of +10 m/s with cero acceleration. The constant velocity +10 m/s
makes a straight line in the graph. Another example is a object moving changing velocity or accelerating. The object is going to the right side (positive …show more content…
The acceleration of an object is the result of any or all forces acting on the object according to Newton second law. The international system of units for acceleration are :
How to find the average velocity, final velocity minus initial velocity divided by time.
An example, let 's find the average acceleration of Vf = 50 m/s, Vi = 0 m/s and a time of 5s.
The average velocity is 10 m/s*2. That was an example of average acceleration. How to recognize direction of the acceleration vector according to the direction of the slope, a slope going to the right is a positive slope and a slope going to the left a negative slope.
Example A: The velocity is increasing 2 m/s every second, so the slope is going to the right from a positive side and it is positive acceleration.
Example B: The velocity is increasing 2 m/s every second, so the slope is going to the right side from a negative side to a positive side and it is a positive acceleration.
Example C: The velocity is decreasing 2 m/s every second, so the slope is going to the right side (downward) from a positive side, it is negative
